sL-PROPELLD v'ErrI'o'LE.

To all whom t may concern:

Be it known that I, Snzo I-IATASHITA, a subject of the Emperor of Japan, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new vand useful Improvement in and declare the following to .be a full, clear,

fand exact description ofthe same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had tothe accompanying drawings, which form a part of this specification. My invention relatesto. self-propelled ve- .hicles and an object of my improvements isk to provide a transmission gear adapted to be usedy when a pleasurevehicle is adapted to ycommercial purposes. w v

I secure this' object in the device illustrated in the -accompanying drawing \1n which:`

Figure 1' isa section of an apparatus em-l bodying my invention and so `much of an automobile as is necessary to illustrate. its

\ connection therewith.

' the rotating flanged cylinder forming apart Fig. `2 is a plan view partly in section of of my inventio Fig. 3 is an end elevation looking from the right of Fig. 2. v

Fig. 4 is a view similar to Fig. 2 show- A `ing a modified construction, and

. wall .outward as shown.

'fords a bearing b3 for the driving shaft o. 'd is a connecting piece yltting in a socket in the end `of the shaft c to connect said shaftk Flg. 5 is an end elevationy looking from the right ofv Fig. y4.` f

wis the rear end of the engine and gear casin of a Ford automobile. Z2 is the semispherlcal shell having a flange b2 secured to a flange at the end of-V the casing a and extending into said casing with its concave with the transmission mechanism.

I provide a piece e having an annular flange at its periphery adapted to t against and be secured to the flange bz'ofthe shell b.

e2 is a bearing coaxial with the bearing b3 formed in Ithe piece-e. and yprovided with a hardened ring e3 around its inner wall. f is a cylindrical rotating part having a ange f2 formed around its rear end and provided with grooves around its periphery.l in one of which grooves iit the rollers g and in the vother of said grooves a dust excluding washer il.. The cylindrical rotating piece f is formed to engage the connecting piece Z Self Propelled Vehicles,

4bearing e? to` exclude the dust from the contiguous parts ofthe bearing. y' is a casing inclosing a universal joint c by which the vpiece f is connected to the transmission shaft m. y

It will be observed that the bearing e2 1s of considerable diameter affording large wearing surfaces and that the piece f affords an arbor carrying its own friction reducing elements g and adapted to be inserted as a whole and withdrawn from the bearing e.

The rollers g may g2, as shown in Figs. 2 and 3, or they may be formed in a cage, as shown in Fig. 4, and slipped over the end of the piece or washer/E, as shown in Figs. 4 and 5.

What I claim is:

l.' In combination with a casing end having a bearing for the power` transmitting shaft, a piece e adapted to be secured to said casing end and provided with a bearing surface coming axially in line with the bearing on said casing end, and an arbor carrying friction reducing means adapted to be inserted and removed from the bearing in the piece e.

2. In combination with a casing end having a bearing for the power vtransmitting shaft, a piece e adapted to be secured to said casing-endand providedwith a bearing surface coming axially in line with the bearing on said `casing end, and an `arbor carrying yfriction reducing' means adapted to be inserted and removed from thefbearing in thepiece e, and in so doing be engaged and disengaged` from the power shaft.

3. In combination with a casing end having a bearing for the power. transmitting shaft, a piece .e adapted` to be secured to said casing end andprovided with a bearing surface coming axially in line with the bearing on said casing` end, and an arbor carrying` friction reducing means adapted to be, inserted and removed from the bearing in the piece e, said arbor being provided with a peripheral groove adapted to` receive a dust excludingwasher for the purpose described.

4. In combination with a casing end having a bearing for the power transmitting be pivoted upon pins I i sodoing to fit within the bearing e2 lso shzii't,4 a piece bearing on sand easingl end, and 5A carrying in the piece e,

Copies of this patent may be obti-ned foi` e adapted to be secured-Y to said easing end and provided with a'bear ing surface coming axially in line with ther` an larbor i'ietionv reducing means adapted vto be inserted and removed from. the bearing said arbor being provided sEzo infmsnifmi.
